I have asked Roly ZL1BQD, a prolific DXpeditioner to come and talk to about everything DXpedition, from the 1-man DX Island hopper through to the multi-person rare DX entity full expedition. What are the problems, what goes wrong..

This is the compact 6.5m vertical antenna resonant on 40m and 20 with the coil at 5.5m above ground level. We also have elements for 15m and 10m.

Beverage On The Ground Antenna – Converting my Long Wire to Beverage Antenna

Post author By admin
Post date March 18, 2023

In this video, I explain how I’m going to change my VERY long wire into a Beverage. Then we’ll look at how this works, what parts I have bought for the project and what results I’m expecting to achieve. I also discuss the difference between a regular Beverage – say 2m or 6 ft off the ground and one that is physcally ON the ground, pinned to the grass with radial pins.

Ham Radio Special – we look at the benefit to YOU working split (5-up) and how to operate in that environment. We look at what does 5-up mean, what does 5-10 up mean and who are the band-police? LOL Callum.

Success! 20m and 40m on same element – Amazing Result!

Post author By admin
Post date March 12, 2023

The placement of a coil on an element affects the third harmonic. If you can work out exactly where to put this coil, we can then force a harmonic on almost any band you like. In this example we have made a compact 40m antenna of only 6.5m long and then made 20m to work on the third harmonic with very little loss. See what you think. Callum.

My Cheap 80 Foot (30m) Home Brew Tower Fell Down!

Post author By admin
Post date March 11, 2023

We destroyed an 80 feet tower in 5 seconds. But the 60 foot version worked GREAT! Full parts list for my home-brew 60 feet tower made from scaffolding poles, connectors and poly rope detailed in this video – and also below. TAKE CARE because if anything goes wrong, you are into an extremely serious accident.

You will need:

– 4 x alloy poles (optionally one in steel)
– About 1,000 feet (330m) poly rope (lorry rope)
– Some sort of tilt-hinge (I have made a couple of these on this channel)
– 3 x straight scaffolding connectors
– 1 cross joiner (for just above the tilt mechanism)
– 2 hinged connectors (if you wanted to make the crossbar)
– At least 4 large guy points (you can home brew from angle iron)
– Selection of 6mm / 1/4 inch bolts to tap the poles for guy points
– at least 3 x 4-way guy points for the scaffolding poles
– Steel carabiners with a decent high rating
– Hard hat (seriously!)
– Know how to tie knots!
